Absolute zero, then, is the point at which all molecular motion stops — minus 459.67 degrees Fahrenheit, or minus 273.15 degrees C.
Scientists have even developed a special scale for extremely cold temperatures, called the Kelvin scale, where zero Kelvin corresponds to absolute zero.
Then, they cooled the chamber way down, to around 2 billionths of a degree Celsius above absolute zero, which would have been a world record in itself, according to NewAtlas. .
The resulting BEC stayed at 38 picokelvins - 38 trillionths of a Kelvin - for about 2 seconds, setting "an absolute minus record", the team reported Aug.
Its average temperature is -272 C (about 1 Kelvin) according to the European Space Agency.
The researchers of the new study said in a statement that, theoretically, they could sustain this temperature for as long as 17 seconds under truly weightless conditions, like in space.Thank you for signing up to Live Science
